A welded pipe electric welding machine with good cooling effect

Abstract

The invention provides a welded pipe electric welding machine with an excellent cooling effect and relates to the field of welded pipe machining. The welded pipe electric welding machine with the excellent cooling effect comprises a first box body, a second box body and cooling boxes, wherein an electric welding machine assembly is arranged inside the second box body; the second box body is positioned in the first box body; two symmetrically distributed cooling boxes are arranged in a gap between the first box body and the second box body; the two cooling boxes are respectively mounted on the outer wall of the second box body; a first air outlet pipe is arranged on the top of the cooling boxes; one end of the first air outlet pipe penetrates through the cooling boxes and extends into the cooling boxes; one side of the outer wall of the first air outlet pipe is communicated with an exit pipe; and one end, which is far away from the first air outlet pipe, of the exit pipe sequentially penetrates through the cooling boxes and the second box body and extends into the second box body. According to the welded pipe electric welding machine with the excellent cooling effect, a cyclic refrigerating effect is achieved, the temperature of the electric welding machine assembly is reduced, and the service life of the electric welding machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of welded pipe processing, in particular to an electric welder for welded pipes with good cooling effect. Background technique [0002] Welded pipe is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high pressure of the welded pipe to the low pressure, and it can also be transported by the pressure or gravity of the fluid itself. Welded pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance oil and natural gas transmission, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] Welding pipe welding machines are mostly used for the connection of welded pipes, but the heat dissipation of most of the welding machines on the market is not good enough. The energy-saving ...

Problems solved by technology

[0003] Welding pipe welding machines are mostly used for the connection of welded pipes, but the heat dissipation of most of the welding machines on the market is not good enough. The energy-saving electric welding machine includes an electric welding machine, which is mainly characterized in that an electromagnetic relay is connected in series in the secondary circuit of the electric welding machine, and a heat dissipation fan is connected in series in the primary circuit of the electric welding machine, and the heat dissipation fan is installed on the top of the electric welding machine. It can blow air downward to dissipate heat for the welding machine. The two circuit terminals of the electromagnetic relay in the secondary circuit are connected in series in the primary heat dissipation fan.

Although the above-mentioned patent has simple structure and easy to use, when the electric welding machine is unloaded, the secondary circuit is not connected, so that the relay does not work; The fan runs to take away the heat of the welding machine, but this patent cannot circulate heat dissipation, and only one cooling fan cannot guarantee the cooling effect, and the cooling effect is not ideal, which will have a certain impact on the service life of the welding machine
